Improvements in Methods of Making Heads for Brooms, of which thefollowing is a specification.

The object of my invention is to provide a method of making heads forbrooms whereby such an intimate union is secured between all parts ofthe inside of the ease or head and the corn-straws of which the broom iscomposed that there is no corner or crevice in which any dust orotherunclean or unsanitary substance can find a lodging-place. At the sametime the heads or cases made by my improved method are light, durable,cheaply made, and of uniform structure.

My improved method of making heads for brooms consists, primarily, instamping out and drawing from a sheet of metal a blank provided with aperipheral flange and depressed to correspond to half the cross-sectionof the case or head to be formed, cutting said blank in two portionsmidway of its length, and trimming the flanges to adapt them forinterlocking each other, associating the two portions thus formedtogether by interlocking the said flanges and forming a complete broomhead or case by forcing the interlocking flanges into intimate union,thereby forming a durable seam. It will be readily understood that thismethod may be applied to broom-heads of different figuration; but theform which I have found most satisfactory,

both for manufacturing purposes and use, is made with tapering androunded shoulders, as shown in the accompanying drawings, in Which-Figure 1 is a top view of the blank as first stamped and drawn from asheet of suitablematerial, preferably tin. Fig. 2 is a top view of saidblank after the flanges have been trimmed, Which is preferably done byplacing the blank of Fig. 1 under a second die. Fig. 3 is a longitudinalsection of Fig. 2. Fig. 4 is a top view illustrating the next stage ofthe operation, which consists in separating the blank into two piecesand perforating each dle socket.

piece along the cut edge. Fig. 5 is an elevation showing the two halvesof the case nearly put together by slipping the narrow flange of onehalf into the doubled-over flange of the other half. Fig. 6 is an endview. Fig. 7 illustrates the next step of the operation namely, theformation of a permanent seam along the meeting edges of the two halvesof the case by compressing the flanges into close contact. Fig. 8 is adetail of the broom-han- Fig. 9 is an elevation, partly broken away, ofthe complete broom-head.

The same letters indicate similar parts in the different figures.

A is one half the body portion of the case. B is the other half.

C C are the two portions of the neck for receiving a handle.

D D represent a tapering screw-socket separately formed and adapted forinsertion in the neck.

The portion A is provided with a peripheral flange a, which is somewhatwider than the peripheral flange b of the other body portion B. Theflange a, therefore, can be bent over npon itself, so as to inclose theflange I), as

. shown in Fig. 6. The perforations c c of the portion A correspond withthe perforations d d, so that when the two portions are brought togetherto form a case the fastening-wire can be passed through from side toside to draw 1 the case down upon the broom-corn.

E is a former upon which the seam 1s compressed, as shown in Fig. 7, theupper half being shown as compressed, while the lower ering of the twoportions shown in Fig. 4 and the perforating thereof might form part ofthe operation of cutting the blank of Fig. 2 from the blank of Fig. 1.

The association of On the other hand, the sev- IOO these two halves, asshown in Fig. 5, is done by hand after the bending over of the flanges,as shown in Fig. 6, which is preferably done by machinery. Thecompression of the seam, as shown in Fig. 7 may be either with arevolving former or horn, in which case onehalf is done at a time, or ona stationary horn, in which case both sides may be compressed at once.

I claim A method of forming heads for brooms which consists first instamping out and drawing from a sheet of metal a blank provided with aperipheral flange and depressed to correspond to half the cross-sectionof the case two portions thus formed, together, by interlocking the saidflanges; compressing the interlocked flanges into intimate union, andlastly inserting a suitable handle-socket whereby a complete broom-headis formed.
